All first officers at EK are currently on the "fast track" command system. As of today, it is taking first officers on the T7 about four years to upgrade on this "fast track" system. A couple of years ago it was taking as little as three years to upgrade on the "fast track" system. Rumour has it that over the coming years and beyond it may take five, seven or some say, over ten to upgrade on the "fast track" system. If this will be the case then the "fast track" system will be renamed the "normal track" system at the companies discretion.
Hope this helps.
